I remember starting to get those looks when I got my first BMW (2000 328i).
My wife always seemed to get the "Who are you blowing for that car?" look and I seemed to get the "What makes you so freakin' special?"

You will always be the envy of your friends. I have this one friend that seems to follow my shawdow and up one on me with cars and well I seem to have left him for the dust in the process. Trying to be the Jones's I guess. Your friends should be happy for you and ask to ride in it for the thrill.
